SPINNING FRAIVIE.

SPECIFICATION forming part of Letters Patent No. 621,255, dated March14, 1899.

Application filed Gotober 19, 1898- Serial No. 693N75- (No modeh) To allwhom it may concern.-

Be it known that I, GEORGE W. KNIGHT, of Hopedale, county of Worcester,State of Massachusetts, have invented an Improvement in Spinning-Frames,of which the fol-' lowing description, in connection with theaccompanying drawings, is a specification, like letters on the drawingsrepresenting like parts.

This invention has for its object the production of simple and effectivelooking or retaining means for holding in place the capbars of aspinning-frame, whereby they may be readily and quickly removed orreplaced without the use of tools.

Figure l is a top or plan view of a portion of a spinning-frame, partlybroken out and showing only one section of top rolls with myinventionapplied to the apparatus. Fig. 2 is an enlarged transversesectional view of the frame on the line m 00, Fig. 1, looking toward theleft; and Fig. 3 is an enlarged rear elevation showing my invention inposition to permit removal of a cap-bar.

The lower rolls R, supported in frames A, carried by the usual stands Aone of which is shown in Fig. 2, and the upper rolls R, arranged insections and having their journals mounted in arms 0 of the cap-bars C,may be and are of usual or welleknown construction in this class ofapparatus.

The cap-bars O are herein shown as removable and cut away at adjacentends, as at 0, (best shown in Fig. 3,) to receive the bearings a, formedat the rear upper ends of the frames A, the ends of the bars when inoperative position abutting against said bearings.

Axial sockets or recesses 0 in the ends of the cap-bars are in alinementwhen said bars are in position and are entered by asliding retainingbolt or keeper d, mounted in the bearing a, the latter having atransverse slot a, to be traversed by a stud-like handle 01 of the boltor keeper.

The keeper is longer than the bearing a and when midway in the latterprojects beyond its sides into the sockets 0 of two adjacent cap-bars,as shown in Fig. 1, retaining them in place.

A locking-slot a intersects the slot at, and in order to retain thekeeper, and consequently the cap-bars, in operative position theactuating-handle d of the keeper is thrown down into this locking-slot,as in dotted lines, Figs. 2 and 3. I

By unlocking the keeper and sliding it in one or the other direction oneof the cap-bars O with which it cooperates will be released, and whenboth keepers of any given cap-bar are withdrawn from engagementtherewith the bar can be at once lifted from the frame.

The keepers serve as fulcra for the cap-bars when in operative positionand provide firm supports therefor.

By the construction herein set forth the use of tools to detach orapply'a cap-bar is entirely obviated.

Having fully described myinvention, what I claim, and desire to secureby Letters Pat'- ent, is

1. In a spinning-frame, a plurality of re movable cap-bars, a fixedbearing interposed between the ends of two adjacent cap-bars, a slidingkeeper carried by and longer than the width of the bearing, to cooperatewhen in mid-position with both cap-bars and provide retaining-fulcratherefor, longitudinal movement of the keeper withdrawing it from andreleasing one or other of the cap-bars, and locking means to retain thekeeper in midposition.

2. In a spinning-frame, a plurality of removable cap-bars provided withlongitudinal sockets at their ends, a fixed bearing interposed betweenthe ends of two adjacent capbars, a sliding keeper carried by thebearing and adapted to cooperate with the cap-bars, or be withdrawn fromone or the other to release them, and a locking device to hold thekeeper in cooperative engagement with both bars.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

GEORGE W. KNIGHT.
